terial, from which the' cup is formed, said blank comprising two'corresponding fiat members 16, 17 and having a crease line 1S @on oneface defining the 'central transverse division between said members; lheniemrging side edges extending -to the ends' of the crease line 18, andin addition the members 16, 17 are formed with crease lines 19, 20, 21,the 'crease lines 19 being transveliseiof the blank yand equally spacedtrom th central transverse line 18, and the crease lines 20 beingextended lengthwise et' the blank parallel with each other from onecrease line 19 to the other crease line 19 and reasonably adjacent tothe side edges of the blank, while the crease clined lines from the endsof the longitudinal crease lines 2O to the crease line 18. The

, crease line 1S defines the line on which the blank is folded, and theother crease lines referred to come into use only when a pros- I pectiveuser of the cup desires to convert the lower end ot' the same into atiatsupporting bottom.

After the blank .has been folded on the line 18 and the members 16, 17have beeii brought in tace to tace contact, the adjacr yc side edgeportionsof said members are securely fastened tdgether and latwiseagainst each other to form a fiat receptacle by means of binding strips22, preferably of metal, which extend from the upper to the lower edgesof said members and are 'approximately of U-shape in cross-section Atoreceive and be firmly compressed against said edge portions of themembers 1G, 17 so as to bind said members together without other meansthan the pressure of the opposite sides ot' said binding strips.'Initially the binding` strips :22 extend slightly above the upperedges' of the members 16, 17 and thereby form projecting portions 2d..shown iii Fig. ritter the strips 2:. have been applied to the side edgesot the inembers 16, 17 to create the construction shown in Fig. Q, saidbinding strips are t'olded over or turned inwardly toward cach otheragainst 7the outer face ot' one ot' said members; in this instance themember 1G, and the upper projecting end portions 23 of said bindingstrips are 'then bent.lateially and downwardly against the inner faceot' said member 1S, leaif'ing the upper ends of the binding stripssmooth and securing said strips against the outer face of the member 16,thereby creating the construction shown iii F ig. 1. Vi'hen the cup hasreached the stage illustrated in Fig. 4, it will have been entirelycompleted and be ready for the market, the cup then being flat andformed of two integral sides fastened together at their vertical edgesby the strips 2Q, with no paste or other adhesive present.

rThe finished cup discloses the crease lines 19, :'20, 21 as a guide andaid to the user of the cup in fashioiiing the lower cud thereof into aflat bottomadapted to support tho cup oii a table, 'tray or the like.The hat cups shown in 'Fig'. l may be very convcn ieiitly carried bothiii stock by a dealer and iii the pocket by persons desiring to use thecups. The cup shown in Fig.- 4 is :i fat cup as distinguished from whatis commonly 75 called a formed-upf cup or one which is permanently incircular shape and has a fixed flat bottom. The paper used in the cup isflexible and of water-proof character and preferably devoid of any waxor other surface-coating. When it ispdesired to use the cup ot myinvention a person may by pressing in wardiy on the middle portion ofthe bottom edge thereof, cause the paper ot' thc cup .to bend at.right-angles to the side members 16, 17 on those portions of the creaselines 19 which are intermediate the crease lines Q0, as indicated inFig. 1U; and

.opposite side or hound edges of the cup slightly toward each other andopen out or distend the. main body portion ot the hotly of the cup, andin addition the liattening of the central portion of the bottom of thecup will form and vleave projecting dowi'iwardly trom the told lines 20,two triangular end .sections 2l which may then be folded iiiwardly onthe crease lines il() and those portions of the crease lines 19 whichare outwardly beyond the lilies 20, against the flat portion definedbetween said lines 2O and the middle portions of the lines 19, :irectangular flat bottom being thus created. as shown in Fig.' 11.suitable to support the cup and such contents as may he placed therein.along the sections 2l, and when said sections are folded inwardly to aidin creating the flat bottoni, said strips serve to preserve theiiitegrity of the flat bot-tom and thus materially aid in creating aVdurable structure and a cup oi such stability as to render its use bothconvenient and safe.

lily invention, therefore, comprises a desirablecupstructure which isinitially flat. and which has on its side members guiding maiis orcrease lines enabling a user to properly and conveniently convert thelower end of the cup into a fiat supporting bot.- tom `which without anyadded means serves to maintain the cup in expanded condition ready foruse. v

l/Vhat claim as my invention and desire to secure by Letters Patent. is:

V1. As a new article of manufacture, an initially flat. drinking cup ofpaper or the like comprising a transversely folded blank 180 the facesof whose side members are clamped together liquid tight at theiradjacent side edges and bear adjacent to their lower ends crease linesto guide the usei. in converting the lower end of the cup into a flatbottom on which the cup may stand.

2. As a new article of 'manufacture an initially flat drinking cup ofpaper or the like comprising a transversely folded blank the faces ofwhose side members are clamped together liquid tight at their adjacentside edges and bear adjacent to their lower ends crease lilies to guidethe user in converting the lower end of the cup into a flat bottom onwhich the cup may stand, said crease lines extendingtransversely of saidmembers suitably above the folded lower edge of the cup, verticallybetween said transverse lines inwardly from the side edges of saidmembers and downwardly and outwardly from the upper ends of saidvertical lines to th lower edge ofthe cup.

As a new article of manufacture, an initially flat drinking cup of paperor the like comprising a transversely folded blank forming the sidemembers of the cup, and bendlable stitfening strips clamped upon andholding together liquid tight the adjacent side edges of said members,said members having adjacent to their lower ends crease lines to `cuidethe user in converting the lower end of the cup into va fiat bottom onwhich the cup may stand.

l. An initially Hat drinking cup of paper or the like comprisingatransversely folded blank forming" the side members of the cup, andbendable stiffening strips applied to and binding together. the adjacentside edges of said members, said members having adjacent to their lowerends crease lines to aid the user in converting' the lower end of thecup into a flat bottone and said lincs extendin n transversely of saidmembers above the lower folded edge of the cup, vertically between saidtransverse lines at points set inwardly from the vertical side edges ofsaid members and diagonally downwardly and outwardly from the upper endsof said vertical lines to the lower edge of the cup.
